ROTARY CAP-CLOSU RE.

SPECIFICATION forming part of Letters Patent No. 749,671, dated January12, 1904.

Application filed Tune 6, 1903. Serial No. 160,369. (No model.)

To a/ZZ whom) it may concern:

Be it known that I, HENRY J. S. HALL, a citizen of the United States ofAmerica, and a resident of the borough of Manhattan, New York city, inthe State of New York, have invented a new and useful Improvement inRotary Cap-Closures, of which the following is a specification.

This invention relates primarily to the closures of receptacles used asoriginal packages for tooth-powder and adapted at the same time forconveniently discharging the contents upon the tooth-brush and to betightly closed so as to be free from liability to the accidental escapeof the powder in travelingbags and the like.

The improved closure is applicable, however, to any box, bottle, or jarfor powders, liquids, or semisolids, and the Vterm box,

as hereinafter employed, is intended to include any such receptacle.

The present invention consists in certain novel combinations ofpeculiarly-constructed parts hereinafter set forth and claimed. Itsdistinguishing objects are toadapt a rotary cap to be turned in eitherdirection in closing the outlet of the box and at the same time to bestopped when the outlet is closed, so as to facilitate and insuresecurely closing the outlet, to wholly relieve the stop device of thestrain due to resisting attempts to remove an externally-applied capprovided therewith, and to .so form and locate a pull-resistingswivel-joint between the rotary cap and an inner cap or cover of the boxthat it shall materially assist in rendering the closure powder-tightwhen the box is closed.

A sheet of drawings accompanies this specification as part thereof.

lFigure 1 is a front view of a tooth-powder box, showing the improvedclosure open. Fig.

2 is a like view of the upper end of the box with the outlet closed.Fig. 3 represents a magnified longitudinal section on the line A B, Fig.2. Fig. 4 representsa plan view with the closure in sectionin the brokenplane indicated by the line C D, Fig. 3. Fig. 5 represents alongitudinal section through a modified closure. Fig. 6 represents across-section on the line E F, Fig. 5; and Fig. 7 is a cross-sectionillustrating another modification.

Like reference letters and numbers indicate like parts in all thefigures.

A tooth-powder box provided with the improved closure comprises threeparts-namely, a body 1, which may be of any suitable material, such assheet metal, paper, wood, or glass, a die-formed cover 2 of suitablesheet metal. as ductile tin-plate or brass, and a dieformed cap 3 of thesame material as the cover 2. The body 1 is preferably provided in anyapproved way with a label a, Fig. 1, indicating the front of the box,and, is 4filled at al tooth powder factory, for example. The cover 2,carrying the cap 3, is then applied and by means of a depending marginaliiange bor its equivalent is or may be inseparably attached to thebody 1. Preferably the cover 2 is so inseparably attached, as iscustomary,

by a circumferential joint, formed by inter` locking said iiange b witha groove b' in the body 1, as in Fig. 3, so as to render it difri-V cultor impossible to refill the box when the original contents are exhaustedin order that the trade-marks and other indicia of said originalcontents may not be misapplied. Such joint bb is also preferably, as iscustomary, both powder-tight and tight as to move ment, so that. thenormally concealed outletopening c of the cover is permanently locatedin front with reference to the label e, and the discharge of thecontents upon a toothbrush is thus facilitated. The other features ofthe cover 2 include a top portion CZ, of any preferred shape, a nozzleportion c, in which said outlet-opening c is formed and which is roundin cross-section, and a preferably closed upper end f at the top of thenozzle e.

The cap 3 comprises a closed upper end g above the nozzle end fand sidewalls 7L, adapted to closely embrace the nozzle-walls e, said side wallsL having an outlet-opening c', adapted to be alined with thenozzle-outlet c, and preferably a milled rim c', by which to turn thecap 3. A swivel-joint j, formed in the -side walls e and /Lfof thenozzle and of the cap parallel to the lower edge of the latter serves toinseparably attach the cap 3 at all points and eectively resist attemptsto remove the locked with each other, but so as to permit the cap 3 tobe readily rotated or turned by the fingers to open or close the box. Bylocating said swivel-joint j below the outletopenings c and c and at ornear the lower edge of the side walls e of the cap 3 it is most readilyformed before the cover 2 is attached and also serves in the mosteffective manner to prevent any leakage of powder at a point which ithas been heretofore impracticable to fully protect without multiplyingthe parts and obstructing the rotation of the cap 3.

Stops and Z4 to limit or control the rotation of the cap 3 are whollyrelieved from strain due to attempts to remove the cap by saidwithdrawal-resisting swivel-joint y' and are thus adapted to performtheir distinctive functions with nicety and to be located, as preferred,either in the ends f and g of the nozzle and cap, as in the speciesrepresented by Figs. l to 4, inclusive, or in the side walls e and 7L ofthe nozzle and cap, as in the species illustrated by Figs. 5 to 7,inclusive, as may be preferred.

In either location of the improved stop device both stops la and It" areformed by indenting the sheet metal, and one of them is elongated in aplane parallel to that of said swiveljoint j' and extends equally onboth sides of the other stop when the outlet is open, so that the rotarycap 3 may be turned in either direction to close the outlet, theextremities of said elongated stop being' located diametrically oppositeeach other, so that the cap when turned in either direction is stoppedwith its outlet-opening c equally and to an ample eX-' tent out of linewith the outlet-opening c in the nozzle. (Compare Figs. 4, 6, and 7.)4In said species (represented by Figs. 1 to 4, inclusive) said elongatedstop It' is formed in the closed top f of the nozzle, and the other stopis formed in the top of the cap 3. In the species represented by Figs. 5and 6 the elongated stop k is formed at the back of the nozzle andprojects inward the same as in the species first named, the other stop'fbeing formed in the cap 3 diametrically opposite the center of theoutlet-opening c' in the cap.

As illustrated by Fig. 7, the elongated stop in either of thearrangements of the stop device may be the stop t", formed in the cap 3,and may project externally, if preferred, and other like modificationswill suggest themselves to those skilled in the art.

Having thus described said improvement, I claim as my invention anddesire to patent under this specification- 1. A rotary cap-closurecomprising a nozzle round in cross-section provided with anoutletopening, and a rotary cap provided with an outlet-opening adaptedto be alined with the outlet-opening first named, said nozzle and capbeing also provided respectively with stops interlocked with each other,and one of said stops being elongated equally on both .sides of theother stop when theoutlet is fully opened, whereby the cap is adapted tobe turned in either direction to close the outlet, and is stoppedwhenever the outlet is fully closed.

2. A rotary cap-closure comprising a nozzle round in cross-sectionprovided in its side walls with an outlet-opening, and a rotary caphaving side walls provided with an outlet-opening' adapted to be alinedwith the outlet-opening first named, and having a. closed upper end,said nozzle and cap being also provided respectively with stopsinterlocked with each other and one of said stops being elongatedequally on both sides of the other stop when the outlet is fully opened,whereby the cap is adapted to be turned in either direction to close theoutlet and is stopped whenever the outlet is fully closed.
